Method of modifying a fluid level sensing assembly by replacing a mechanical float

Abstract

A level sensing assembly senses the level of a fluid in a tank. The tank includes a fluid port that is disposed below the level of the fluid and an air port disposed above the level of fluid. The level sensing assembly includes a lower port in fluid communication with the fluid port of the tank. An upper port is in fluid communication with the lower port of the tank. A measuring vessel is disposed between the lower and upper ports and is in fluid communication therebetween. The measuring vessel includes an auxiliary port disposed adjacent the upper port. The level sensing assembly also includes a level sensor extending down through the auxiliary port into the measuring vessel to measure the level of the fluid in the measuring vessel and the level of the fluid in the tank.

1. A method for modifying a level sensing assembly having a measuring vessel with a lower port, an upper port, an auxiliary port, a set of tricock ports and a mechanical float port having a mechanical float extending therethrough into the measuring vessel, wherein the method includes the use of a level sensor having an elongated body with a defined length, the method comprising the steps of:
 unsealing the mechanical float port; 
 removing the mechanical float therefrom; 
 sealing the mechanical float port after the step of removing the mechanical float therefrom; 
 opening the auxiliary port; 
 inserting a level sensor into the auxiliary port; and 
 sealing the level sensor within the auxiliary port. 
 
     
     
       2. A method as set forth in  claim 1  including the step of orienting the level sensor vertically within the measuring vessel. 
     
     
       3. A method as set forth in  claim 2  including the step of orienting the level sensor vertically within the measuring vessel along the entire length of the level sensor. 
     
     
       4. A method as set forth in  claim 3  including the step of removing a tricock from one of the set of tricock ports. 
     
     
       5. A method as set forth in  claim 4  including the step of securing a shut-off sensor to the one of the set of tricock ports. 
     
     
       6. A method as set forth in  claim 5  including the step of securing the tricock to the shut-off sensor. 
     
     
       7. A method as set forth in  claim 6  wherein the step of removing a tricock includes removing the tricock from a lower most one of the set of tricock ports.
